DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] The preferred embodiment of the anti-blockage gastrointestinal continuous negative pressure aspirator provided by the utility model is as follows: Figures 1 to 5As shown: a blockage-resistant gastrointestinal continuous negative pressure aspirator, comprising a box body 1, a spring column 2 is fixedly connected to the left side of the box body 1 by screws, a negative pressure bottle 3 is fixedly connected to the left side of the spring column 2, a motor 4 is fixedly connected to the back of the box body 1, a rotating rod 5 is fixedly connected to the output end of the motor 4, two groups of push plates 6 are rotatably connected to the surface of the rotating rod 5, two groups of force plates 7 are fixedly connected to the surface of the negative pressure bottle 3, a through hole 8 is opened on the top of the negative pressure bottle 3, a retaining ring 9 fixedly connected to the top of the negative pressure bottle 3 is arranged on one side of the through hole 8, and a drainage tube 10 is inserted into the retaining ring 9.

[0028] In this embodiment, the spring column 2 forms a detachable structure with the box body 1 through screws. The spring column 2 is perpendicular to the box body 1 and the negative pressure bottle 3. When the push plate 6 rotates to avoid contact with the force-bearing plate 7, the force-bearing plate 7 will drive the negative pressure bottle 3 back to its initial position under the action of the spring column 2.

[0029] In this embodiment, the two groups of force plates 7 are located on the movement trajectory of the two groups of push plates 6. The two groups of push plates 6 form a synchronous rotation structure through the rotating rod 5. When the push plates 6 rotate, thrust is applied to the two groups of force plates 7, so that the force plates 7 pull the spring columns 2 to move to the left.

[0030] In this embodiment, the negative pressure bottle 3 forms a shaking structure through the push plate 6 driven by the spring column 2. When the push plate 6 continues to rotate, it will continue to intermittently push the force plate 7, and the force plate 7 will also drive the negative pressure bottle 3 to shake through the spring column 2, so as to vibrate the viscous material stuck in the through hole 8.

[0031] In this embodiment, a rubber ring is provided on the contact surface between the retaining ring 9 and the drainage tube 10 , and the drainage tube 10 is located directly below the drainage tube 10 . By providing the rubber ring, the rubber ring can prevent the drainage tube 10 from sliding down inside the retaining ring 9 .

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of the anti-blockage gastrointestinal continuous negative pressure aspirator provided by the present invention is as follows: Figures 1 to 5 As shown: a water collecting box 16 is fixedly connected to the top of the box body 1, a water pipe 15 is fixedly connected to the side of the water collecting box 16, a transmission rod 13 is fixedly connected to the tail of the water pipe 15, a push ring 14 is fixedly connected to the tail of the transmission rod 13 through a thread, an electric push rod 11 is fixedly connected to the left side of the box body 1, and a force block 12 fixedly connected to the transmission rod 13 is fixedly connected to the output end of the electric push rod 11.

[0034] In this embodiment, the interiors of the transmission rod 13 and the push ring 14 are both hollow, and the center of the push ring 14 is located at the same point as the center of the through hole 8. When the push ring 14 continues to move, water will continue to spray out, thereby playing a role in diluting the thick material so that the thick material will no longer get stuck in the through hole 8.

[0035] In this embodiment, a water spray hole is provided on the side of the push ring 14, and the water spray holes are distributed in a ring shape about the center of the push ring 14. The water collecting tank 16 will transmit water to the interior of the push ring 14 through the water pipe 15. At this time, the water will be discharged from the water spray hole provided on the side of the transmission rod 13.

[0036] The working principle and use process of the utility model are as follows: First, when using the device, first, insert the drainage tube 10 into the part that needs drainage, and then open the device for drainage. Since the foreign matter will fall into the interior of the negative pressure bottle 3 through the drainage tube 10 from the through hole 8, the foreign matter drained out may be viscous, which may cause the through hole 8 to be blocked, and then cause the port of the drainage tube 10 to be blocked, so that the foreign matter inside cannot be discharged normally. At this time, the rotating rod 5 can be controlled by the motor 4 to rotate. When the push plate 6 rotates, the two groups of push plates 6 will apply thrust to the two groups of force plates 7, so that the force plates 7 pull the spring columns 2 to move to the left. When the push plate 6 rotates and does not contact the force plates 7, the force plates 7 will drive the negative pressure bottle 3 back to its initial position under the action of the spring columns 2. When the push plate 6 rotates continuously and pushes the force plates 7 intermittently, the force plates 7 will also drive the negative pressure bottle 3 to shake through the spring columns 2, so as to vibrate the viscous material stuck in the through hole 8.

[0037] By setting the push ring 14, the electric push rod 11 can be opened to push the transmission rod 13, so that the transmission rod 13 drives the push ring 14 to move inside the retaining ring 9. By setting the water collecting tank 16, the water collecting tank 16 will transmit water to the inside of the push ring 14 through the water pipe 15. At this time, the water will be discharged from the water spray hole set on the side of the transmission rod 13. When the push ring 14 is constantly moving, the water will also be continuously sprayed out, so as to play a role in diluting the thick material, so that the thick material will no longer be stuck in the through hole 8.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
